Formula Used

Electricity Consumption Formula

The electricity consumption is calculated using the following formula:

Consumption (kWh) = (Wattage × Hours per day × Days in month) ÷ 1000

Where:

  • Wattage = Power of the appliance in watts
  • Hours per day = Number of hours the appliance is used each day
  • Days in month = Number of days in the billing month (typically 30 days)

The cost is calculated by multiplying the consumption by the current electricity rate in Tamil Nadu.

Assumptions

Key Assumptions

  • Standard billing month of 30 days
  • Current electricity rate in Tamil Nadu (as of latest available data)
  • Appliance wattage is accurate and consistent
  • Usage patterns remain consistent throughout the month

These assumptions provide a reasonable estimate, but actual consumption may vary based on individual usage patterns and electricity rates.

Worked Example

Example Calculation

Let's calculate the electricity consumption for a 100-watt light bulb used for 5 hours each day.

Consumption = (100 × 5 × 30) ÷ 1000 = 15 kWh

At a rate of ₹8 per kWh, the estimated cost would be ₹120.

This example shows how the calculator can help you understand your electricity usage and costs.
